Re: Access GPIO pins over Lua

Hi, with Luajit, one could use FFI to access NuttX GPIO functions directly. But I am afraid that Luajit is currently available only for CM7. On the other hand, one can write standard Lua extension in C and use it with plain Lua to access GPIOs. There are numerous examples of how to do it on intern

Re: Rust in the OS?

-1 from me for Rust in the kernel, +1 for Rust in apps Mixing languages in the kernel was never a good idea. Kernel should follow "as simple as possible" philosophy whenever it could. My opinion is that although Rust is safer than C, if you know what you are doing, a C is good enough. If you don't

Hi, I have accidentally written a lot of files on my sdcard and now I would like to delete them. I have tried with rm * command and it doesn't work. Is there a way to delete multiple files without formatting the card? Regards, Jernej

Assert macro causing problems when building Sqlite

Hi, the same problem as new UNUSED macro was causing me problems when building external libraries, like LuaJIT, an assert macro is also causing problems when building Sqlite3 library. Sqlite code has a lot of assert statements which are usually excluded when NDEBUG is set. But when assert is defin

Hi, I would like to use Sqlite on NuttX and I have managed to successfully build the Sqlite3 library. When running the library, I have noticed that Sqlite is using fcntl F_SETLK and F_SETLKW for locking and those are not implemented on NuttX. Is there a plan to implement this in the future? Regard

Never mind. I have found a solution in the Nuttx Shell documentation, where the CONFIG_SCHED_WAITPID option is described to force synchronous builtin app execution, instead of asynchronous. On Tue, Jan 23, 2024 at 6:19 PM Jernej Turnsek wrote: > Hi, > I would like to develop my own b

imxrt interrupt locking

I am developing a driver which is processing peripheral interrupts every 6.4 microseconds and every 16th interrupt calling notify function from HP work queue. But scheduling workqueue does lock interrupts (through critical section) up to 20us sometimes, causing my peripheral missing interrupts. The

ESP-Hosted on NuttX

Hi, has someone make an effort to bring ESP- Hosted to NuttX OS. ESP-Hosted supports Linux integration and RTOS integration. One could use the RTOS way to bring ESP-Hosted up, but on the other hand NuttX is more like Linux. What do you think? Regards, Jernej

Hi All, when building the latest NuttX OS from git, I am having problems with .version file, where wrong version is used. Running the git describe, I get nuttx-8.2-12100-g56c6943311, although I have the latest code. I have updated the local repo from upstream with --prune and --prune- tags option

Hi, I am trying to set O_NONBLOCK flag with the help of fcntl on Local Socket structure (AF_UNIX) and I am not getting the non blocking functionality. If setting the SOCK_NONBLOCK flag while creating the socket, it is working fine. I am using some Linux based code, where this functionality is work

Interesting problem with mm_heap_s and mm_semaphore

Hi, I am using mm_heap region from address space which starts with 0x. ITCM memory on NXP i.MX RT10xx processors has this address. in mm_heap_s structure, mm_semaphore is the first element and when initialized, it is compared to NULL, thus initialization fails. To get around this problem I
